WINDOW SASH AND FRAME.

Specification of Letters Patent.

Patented Mar. 16, 1915.

Application filed April 3, 1913. Serial No. 758,623.

To all whom it may concern:

Be it known that I, DOMENICK PRnsTERA, a citizen of the United States, residing at Bradford, in the county of McKean and State of Pennsylvania, have invented certain new and useful Improvements in Win dow Sashes and Frames, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in window sashes and frames.

The object of my invention is to provide a window sash and frame in which the sash can be readily removed and access readily had to the weights controlling the sash and at the same time providing means whereby a tight joint is formed to prevent any passage of air from the outside through the frame.

Another object of my invention is to provide a window sash in which the window panes are readily removable and yet firmly held in the sash, whereby the panes can be removed and a screen placed in the same groove in which the window pane was held.

A still-further object of my invention is to provide a simple, cheap and more effective sash and frame having certain details of structure hereinafter more fully described.

In the accompanying drawings-Figure 1 is a side elevation of a window frame and sash embodying my invention. Fig. 2 is a transverse sectional view taken on the line 2-2 of Fig. 1. Fig. 3 is a vertical sectional View of the upper sash showing the screen carried thereby when the window frame is in place. Fig. 4 is a vertical sectional view of the lower sash, showing the screen in place of the glass and showing the removable means for holding the screen in position and also a locking means for holding the lower sash in its lower position.

Referring now to the drawings, the frame consists of outer strips 2, and connected by vertical strips 3 forming the frame. The said strips 3, as shown, are provided on their inner edges with tongues 4, which extend into the grooves 5 carried by the inner face or finishing strip 6, whereby a tight joint is formed to prevent any air from passing inwardly through the Weight spaces 7, in which the weights 8 are arranged. The strips 6 are readily removable and are held in place by screws 9, whereby access is readily had to the weight spaces 7 The strips 3 form guides for the sash 10 and 11, all of which is well understood and needs no further description. The wall of the building extends between the strips 6 and 2, as shown in Fig. 2 of the drawings.

My improved sashes are of the modern construction and the upper sash 10 is constructed precisely like the lower sash 11, but instead of having the usual groove for putty for holding the window panes 12 in the sash, I provide the frame with the overlapping ledge forming the groove 14 and the upper ends of the sash are cut away as indicated at 16. The ends of the cut-away portions 16 are beveled, as indicated at 17, and into which a strip 18 having correspondingly beveled ends 19 fits. This strip 18 on the lower sash is provided with handles 20, by means of which it is moved. The strip 18 is provided with downwardly extending portion 21 which overlaps the upper end of the window pane and firmly holds it within the sash. The window-pane simply slides within the grooves and it will be seen that it is readily removable by first removing the strip 18.

The strip 18 of the upper sash is not provided with handles as it is essential that the sash go up jam against the upper end of the window-frame to form a tight joint therewith. This strip in the upper sash could be secured by transverse screws, or in any other desired manner.

The upper sash 10 around the edge of the pane of glass on the inner face is provided with a recess 22, in which fits the screen 23 held therein by small turn-buttons 24. This enables the screen to be at all times carried by the sash and in a place to be readily had when it is desired to be used in either the upper or lower sash. The removal of the strip 18 and pane of glass 12 allows the screen 23 to be slid down in the pane grooves 14 and the strip 18 is placed in the sash in the same manner as when the panes are used and thus the screen is held in the sash and can not be removed as long as the sashes are in their normal closed positions.

In order to lock the lower sash and also provide means for holding the strip 18 of the lower sash in its downward position, I provide a pivoted member 25 secured to the upper end of the lower sash 11, by means of the plate 26. The said member 25, when in its normal position, is over the strip 18 and thus the said plate cannot be moved upwardly. Connected to the said member 25 on each side of its pivot 27, is av rod 28 and 29 extending outwardly and passing through the guide plates 30 and 31 carried by the upper end of the sash. These rods extend beyond the sides of the sash and enter openings 32 and 33 in the strips 3 of the window frame. Carried by the inner end of the pivoted member 25 is a lug 34 to which is attached a spring 35, the opposite end of the spring being secured to the sash at 36. This spring, as shown, is a coiled spring and normally holds the member 25 in the position shown in Fig. 2 of the drawings. When it is desired to raise the sash the member is turned to the left, which withdraws the rods 28 and 29 from the openings 32 and 33 of the frame and allows the sash to be readily raised. The plate 26 is provided with a. stop 37 which limits the movement of the member 25 to the right, as shown in Fig. 2 of the drawings.

In a window-sash of this character it will be seen that the panes can be readily removed for washing or when painting the sash, or when it is desired to place a screen in the window and when the sashes are in their closed positions, it is impossible to remove the screen and thus the window will afford the same protection as if the window pane was in the sash.

Having thus described my invention, What I claim and desire to secure by Letters Patent is:

1. A sash having a groove in three sides to receive a window-pane, a vertically sliding strip adapted to close the fourth side of the sash, a horizontally pivoted member secured to the sash and adapted to operate a lock for locking the sash and at all times extending over the strip during the operation of the lock.

2. A sash having a groove in three sides to receive a Window-pane, a sliding strip adapted to close the fourth side of the sash, a horizontally pivoted member secured to the sash and extending over the sliding strip, a lock operated by the pivoted member, and said pivoted member constructed and arranged to at all times extend over the sliding strip during the ordinary operation of thelock.

3. A sash having a groove in three sides to receive a window-pane, a vertically sliding strip closing the fourth side, a horizontally pivoted member secured to the upper edge of the sash, a sliding bolt secured to the said pivoted member on each side of the pivot, and adapted to lock the sash, and said pivoted member constructed and arranged to at all times extend over the sliding strip during the normal operation of sliding the bolts.

In testimony whereof I hereunto afiix my signature in the presence of two witnesses.
